GLP-1/GCG Dual Agonist in Type 2 Diabetes With Early Dementia (LIGHT-COG Study)

Efficacy, Safety, and Tolerability of a GLP-1/GCG Dual Receptor Agonist in Type 2 Diabetes With Early Dementia: A Multicenter, Randomized, Parallel-group, Double-blind, Placebo-controlled Trial


Sponsor

The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School

Enrollment

420 participants

Start Date

Sep 27, 2025

Study Type

INTERVENTIONAL

Conditions

Summary

The LIGHT-COG study is a 76-week, multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial. A total of 420 type 2 diabetes patients with early dementia are randomized 1:1 to either the active treatment group (receiving subcutaneous injections of mazdutide weekly, with stepwise dose escalation to a maintenance dose per protocol) or the placebo group (receiving matched placebo injections). The primary objective is to evaluate the potential disease-modifying effects of mazdutide on cognitive dysfunction in type 2 diabetes.

Plain Language Summary

Simplified for easier understanding

This study is testing whether a medication that works on two gut hormones (GLP-1 and glucagon) can help improve memory and thinking in people who have both type 2 diabetes and early signs of dementia. Researchers want to see if better blood sugar control can also slow memory decline. **You may be eligible if...** - You are between 50 and 75 years old - You have been diagnosed with type 2 diabetes - You have mild memory or thinking problems (mild cognitive impairment or early dementia), with memory complaints lasting at least 6 months - Your blood sugar (HbA1c) is between 7.0% and 9.0% - Your diabetes treatment has been stable for at least 3 months - Your weight has been stable for at least 3 months **You may NOT be eligible if...** - You use injectable insulin other than once-daily basal insulin - You have been on certain memory medications for less than 3 months - You have a significant history of other serious illnesses - Your BMI is under 20 Talk to your doctor to see if this trial is right for you.

Interventions

DRUGMazdutide

Mazdutide injection (pre-filled auto-injector pen) is administered subcutaneously at the same time each week. The starting dose is 2.0 mg administered once weekly (QW). Based on individual patient tolerance, the dose should be gradually increased to the target therapeutic dose of 4.0 mg QW over a period of 4 to 12 weeks. The protocol permits adaptive dose escalation up to 6.0 mg weekly when clinically indicated. For participants unable to tolerate dose increases, treatment continue at their maximum tolerated dose. The total intervention duration is 76 weeks.

DRUGPlacebo

Placebo injection (pre-filled auto-injector pen) is administered subcutaneously at the same time each week. The starting dose is 2.0 mg administered once weekly (QW). Based on individual patient tolerance, the dose should be gradually increased to the target therapeutic dose of 4.0 mg QW over a period of 4 to 12 weeks. The protocol permits adaptive dose escalation up to 6.0 mg weekly when clinically indicated. For participants unable to tolerate dose increases, treatment continue at their maximum tolerated dose. The total intervention duration is 76 weeks.
